I live in an old terraced house and have the only downpipes (front and rear) for my guttering, the house next door and half of the pub next to that! I wish to know if I can seperate my guttering from the rest ( giving an appropriate warning to the neighbours ) as my downpipes cannot cope with heavy rain causing damp in my property
In a similar way to drainage, your neighbours are likely to have a easement to allow their storm water to flow into your guttering for dishcarge. as a rule of thumb a standard uPVC rain water pipe can handle up to a 50sqm roof. I think you could run into trouble if you do anything that interupts to flow of water and causes problems to your neightbour properties. Few suggestions:
1. Speak to your neightbours. Explain the problem and see if one of them will accommodate a rain water pipe in their land. The guttering may need to be altered to re-direct flows. Obviously raise the issue of shared costs?
2. Above is likely to go down like a lead balloon, so I suggest replacing your guttering with a deep flow (which has a greater capacity) and think about increasing the size of the down pipes.
Many thanks for the reply, Unfortunately I have tried to persuade several different neighbours over the years to fit another downpipe - to no avail ! the property is in a conservation area and so larger guttering is out. I have had this problem for 20 years, also getting fed up every autumn of cleaning first the leaves from my guttering then everyone elses as they wash down to my downpipes and block them. Cheers Mike
first and foremost, each individual homeowner has an obligation (ground conditions permitting), to drain their storm water upon their own land.
failing this, and without the convenience of a storm drain system, then lie of the land becomes prevalent. if gravity dictates that normal ground water would fall towards your property, then i guess you had better prepare your guttering to better deal with the added influx of the neighbours rainwater.
